【选型】容耦通信隔离芯片SI8600AB-B-ISR可替代ADUM1250SRZ,可实现更快的通信信号响应
在混合动力汽车电池管理系统设计时,为确保控制芯片不被采集的动力电池信息信号干扰,以及防止动力锂电池组产生的过压过流等对控制芯片造成破坏,需要对两侧浮动的电源和地进行电气隔离,市面上有采用双向通信总线连接的I2C通信隔离设计,选用ADI公司ADUM1250SRZ的磁耦通信隔离芯片设计,可参考如下电路示意图。
图1:由磁耦隔离芯片ADuM1250构成的I2C双向总线隔离电路示意图
不过,因磁耦通信隔离易受电磁场干扰,本文重点推荐SILICON LABS(芯科科技)的容耦通信隔离芯片SI8600AB-B-ISR替代ADUM1250SRZ进行改善,典型电性参数对比参考如下图1所示。
图1:通信隔离芯片SI8600AB-B-ISR与ADUM1250SRZ典型电性参数对照表
通过如上图易知:
1、Silicon Labs的通信隔离芯片SI8600AB-B-ISR相比ADI公司的ADUM1250SRZ在最大传播延时和共模瞬态抑制特性参数上表现更出色的特性参数:
1)、最大I2C总线数据传输速率达1.7Mbps,最大传播延时低至20ns,可实现更快的通信信号响应;
2)、最低共模瞬态抑制达35kV/μs,具有更出色的共模干扰抑制能力;
图2:通信隔离芯片SI8600AB-B-ISR与ADUM1250SRZ pin脚定义示意图
通过上图易知:
2、Silicon Labs的通信隔离芯片SI8600AB-B-ISR与ADUM1250SRZ均采用SOIC-8封装,且pin脚定义完全相同,可实现pin-pin兼容替代。
除去上面介绍的技术优势外,Silicon Labs的通信隔离芯片SI8600AB-B-ISR还有以下竞争优势:
世强大批量备货,交期短,更好的供货周期,可快速支持样品和后续量产品服务。
综上,采用Silicon Labs的通信隔离芯片SI8600AB-B-ISR可以较好地替代ADI公司的SI8600AB-B-ISR。
